Definitions
- the repair detail is formed with a pilot hole that extends through the repair detail, but is of a smaller diameter than the remaining bore portion.
- a repaired variable vane is inserted into a variable vane system within a gas turbine engine.
- a method of repairing a variable vane having an airfoil, an inner trunnion shaft and an outer trunnion shaft, with the outer trunnion shaft having a threaded hole and a groove extending around a circumference of the outer trunnion shaft includes the steps of removing a portion of the outer trunnion shaft at a location between the airfoil and the groove leaving a shaft stub.
- a repair detail is prepared having an outer peripheral shaft portion with a nominal outer diameter.
- the repair detail further has a pilot portion extending forwardly and having a smaller outer diameter than an outer diameter of the nominal outer diameter.
